Ball Joint 3,603 OE numbers
What this part does
Steering and suspension articulation
The ball-shaped stud rotates freely inside its socket, allowing the knuckle to swivel for steering input AND tilt vertically as the suspension compresses and extends — both motions through a single compact joint.
Load-bearing vs follower
On a standard control-arm/strut layout the lower ball joint is load-bearing (carries vehicle weight) and the upper joint, if present, is a follower (positions the knuckle but carries no vertical load). On a double-wishbone suspension both joints share the load.
Camber and caster anchoring
The two ball joints (or one ball joint plus the strut bearing) define the steering axis. Joint wear shifts that axis, throwing camber and caster out of spec.

How OE cross-referencing works
An OE (original equipment) number is the part number a vehicle maker gives a component. Each part in this catalogue is listed under the OE numbers it replaces and under the equivalent numbers other parts makers use, so the same part can be found from any of those codes.
Search an OE number to see the matching part, the vehicles it fits and its full cross-reference list. SLOOP parts are aftermarket replacements; vehicle brands and OE numbers are cited only to identify fitment. Search →

What is a ball joint?
A ball joint is the spherical bearing that connects a suspension control arm to the steering knuckle — the pivot that lets the front wheel steer left and right while also moving up and down with the suspension. Modern independent front suspensions have one or two ball joints per side; ball joints are also used at some rear-suspension and 4×4 driveline locations.
How many ball joints do you carry?
